ETA2840
ETA2840 is 1A Step-Down LED Driver manufactured by ETA.
DESCRIPTION
FEATURES
The ETA2840 is a wide input range, high-efficiency,
- Wide Input Operating Range from 4.5V to 36V and high frequency DC-to-DC step-down LED
- Standoff Input Voltage: 42V driver, capable of delivering up to 1.5A of output
- High Efficiency PFM mode at light load current. ETA2840 provide 0.16V feedback voltage,
- Capable of Delivering 1.5A which minimize the power loss on the sense resistor
- No External pensation Needed in a LED driver system. With a fixed switching
- Current Mode control frequency of 600KHz, This current mode PWM
- Logic Control Shutdown controlled LED Driver allows the use of small
- En can be controlled by ambient light external ponents, such as ceramic input and
- Thermal shutdown and UVLO output caps, as well as small inductors. ETA2840
- Available in SOT23-6 Package also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high
APPLICATIONS efficiency operation. An OVP function protects the
- IR LED driver for surveillance camera
IC itself and its downstream system against input
- LED lighting voltage surges. With the hysteresis, EN can be
- Constant current source controlled by the ambient light-sensitive resistor.
ETA2840 is available in a space-saving SOT23-6 package.
